Insight for: Show HN: I Was Here – Draw on street view, others can find your drawings

'I Was Here' is a niche consumer-facing application leveraging geospatial data and real-time rendering. Its core value proposition is ephemeral digital graffiti on real-world street views, fostering a unique form of social interaction and persistent digital presence. The use of WebGL2 for 3D projection and Mapillary for imagery indicates a technically sound implementation for its specific purpose. Market implications: This is primarily a novelty or social experiment, not a B2B SaaS product. It lacks clear monetization paths or enterprise utility. While it demonstrates technical capability in geospatial rendering, its market impact is limited to consumer engagement and digital art communities. No direct B2B SaaS implications.
